The original example of this pin that I have seen, featured slightly uneven lettering to both sides. It was also individually numbered on the verso with a font resembling that of a Golden Party Badge. Also, the blue enamel filled the voids between the star's rays- those areas that have taken on a white/silver hue (plating?) on the above example.
Unmarked, with a "Ges. Gesch." on the verso. Even though the pin in question was a ground-dug example and not in the best of shapes, it did feature what appeared to be a translucent blue enamel surrounded by a opaque white one, like the one above.
To date, it was the only one that I believe was an original example of this badge. Unfortunately, it was not available for purchase.
